relative_humidity_from_mixing_ratio#
- metpy.calc.relative_humidity_from_mixing_ratio(pressure, temperature, mixing_ratio)#
Calculate the relative humidity from mixing ratio, temperature, and pressure.
- Parameters
pressure (
pint.Quantity
) – Total atmospheric pressuretemperature (
pint.Quantity
) – Air temperaturemixing_ratio (
pint.Quantity
) – Dimensionless mass mixing ratio
- Returns
pint.Quantity
– Relative humidity
Notes
Formula based on that from [Hobbs1977] pg. 74.
\[rh = \frac{w}{w_s}\]\(rh\) is relative humidity as a unitless ratio
\(w\) is mixing ratio
\(w_s\) is the saturation mixing ratio
Changed in version 1.0: Changed signature from
(mixing_ratio, temperature, pressure)
